Abstract

A cooling device in an engine bay of a motor vehicle has a radiator and a radiator louver with at least one lamella that controls the passage of a gas flow through the radiator. At least one bypass duct bypasses the radiator and can be closed off by an associated closing element which is operatively connected to the radiator louver in such a way that an opening of the radiator louver generates a closing of the closing element, and therefore of the associated bypass duct, and vice versa. The radiator louver and the at least one closing element are coupled to one another in such a way that, regardless of the position of the lamellae of the radiator louver and the position of the at least one closing element, an at least approximately uniform lift force, or an at least approximately uniform pitching moment, is imparted to the vehicle.
